STM32756G_EVAL BSP User Manual: stm32756g_eval.c File Reference

This file provides a set of firmware functions to manage LEDs, push-buttons and COM ports available on STM32756G-EVAL and STM32746G-EVAL evaluation board(MB1167) from STMicroelectronics.

            This driver requires the stm32756g_eval_io.c/.h files to manage the 
            IO module resources mapped on the MFX IO expander.
            These resources are mainly LEDs, Joystick push buttons, SD detect pin, 
            USB OTG power switch/over current drive pins, Camera plug pin, Audio
            INT pin
            The use of the above eval resources is conditioned by the "USE_IOEXPANDER"
            preprocessor define which is enabled by default for the STM327x6G-EVAL
            boards Rev A. However for Rev B boards these resources are disabled by default
            (except LED1 and LED2) and to be able to use them, user must add "USE_IOEXPANDER"
            define in the compiler preprocessor configuration (or any header file that
            is processed before stm32756g_eval.h).
            On the STM327x6G-EVAL RevB LED1 and LED2 are directly mapped on GPIO pins,
            to avoid the unnecessary overhead of code brought by the use of MFX IO 
            expander when no further evaluation board resources are needed by the 
            application/example.
            For precise details on the use of the MFX IO expander, you can refer to
            the description provided within the stm32756g_eval_io.c file header
